Blackberry Push Notifications (Local Notifications)

Can you set up Notifications on the blackberry without a server?

I wish to use the equivalent of Push Notifications, but I don't really need a server to decide when to push as it's really just calendar pre-set dates.

Any help thoughts /comments most appreciated

Cheers

where is the calendar itself? (device or backend server) If it's all on the device then your app can simply sleep until the next calendar pre-set date occurs.
